There seems to be a new way to ID where you are Mapcode (

Many distrust the government organisations to just readily hand over our private data to ever more 'helping organisations' that we have to comply with. We end up without a choice and so it becomes a trust and privacy issue. (As has been stated).
Aside: The RAF will soon end the helicopter rescue side of our services (very sad IMHO), and a private organisation will take over.
I agree that as long as I can turn it off or refuse to have it then fair enough.
My sat nav might be able to offer this service and frankly ought to if free AND, and only IF, absolutely NO other data is made available to them without my strict permission.
I know that our mobile phone signals plot our movements for those nosy officials who might decide to locate us at any point! Worrying in itself!
How soon (if not already planned), before they just say lets use this 'service' to track our every move? First make it have a 'convincer', the genuine helpful service then, once people are sold on that you add 'other' services!

I am concerned but the principal is fair. I guess if the 'car' activated it, but only ever on an accident, like when doors or fuel can activate or 'trip' that might be more acceptable.
Trust is so quick to lose and so very hard to regain.
